准据

As far as I know there are three kinds fo such tests commonly exist - the Dall Null test which uses a single plano-convex lens, an auto-collimating test uses a flat as big as the mirror under test and Offner test using two plano convex lens.

据我所知现时一般存有3种此类测试，其一是达耳零位测试采用单一只平凸透镜，再有是自准直测试采用一块平镜大小一如被测试的反射镜，及 Offner 测试采用2只平凸透镜。

As we have learned, this " 2009 cheerful female voice " contest is made with distinguish somewhat before, altogether cent is 3 phase: Phase of countrywide preelection phase, 300 strong break out of an encirclement and whole nation follow finals and total final level.

据了解，此次"2009快乐女声"的赛制与以往有所区别，一共分为三个阶段：全国预选阶段、300强突围阶段及全国准决赛和总决赛阶段。

For example, U-space is uniformly regular and which makes it has fixed point property, U-space is uniformly non-square and thus super-reflexive, uniformly convex space and uniformly smooth space are U-spaces, and an Banach space is an U-space iff its dual space is U-space, etc. In1990s, a lot of work had been done on U-space theory, e.g., Tingfu Wang and Donghai Ji introduced the concepts of pre U-property and nearly U-property. Under the structure of Orlicz space, they made systematic investigation of these properties, and gave the criteria for an Orlicz space to have U-property.

U-空间具有一致正规结构进而具有不动点性质；U-空间是一致非方的，进而也是超自反的；一致凸空间和一致光滑空间是U-空间；Banach 空间为U-空间的充要条件是其对偶空间为U-空间，等等。20世纪90年代，国内外学者对U-空间理论做了很多工作，王廷辅，计东海等人先后引入了准U-性质与似U-性质的概念，并在Orlicz空间框架下对有关性质进行了系统研究，完整给出了Orlicz空间具有各种U-性质的判据。

According to an authoritative department statistics: the number of smokers in the total population of 42%, while 1.5 billion Chinese people in smokers is our friends cigarette holder prospective consumers.

据权威部门统计：烟民占总人口数量的42％，而中国15亿人中的烟民正是我们诤友烟嘴的准消费群。

据透露，这份已上报信息产业部的半官方报告是国内第一次对正在进行的TD-SCDMA&准商用&测试进行的全面总结。

The split between the two groups can hardly be papered over.

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
